The easiest way to achieve this swing arm and handling thing would be to use a late 50's pre unit thunderbrd frame and adapt it to take the Sq4 engine /gearbox or better a commando type box 5 speed version to cut down the cruise revs. Those Triumph frames aren't bad at all. Nev

Do it.
I only once rode my dad's plunger framed '57 MkII and found it going round corners like a square (pun intended) block of wood.
How come only Norton's deserve the name 'Gardengate' !

HI Nortons have got a lot better made frames, that is why so many bikers use them to build their bikes
